Raiders cut Matt Flynn (updated)

The Raiders have released backup quarterback Matt Flynn, league sources confirm.

Oakland traded a 2014 fifth-round pick and a conditional 2015 draft pick to the Seahawks to acquire Flynn and the two seasons that remained on his three-year, $19.5 million contract. He was guaranteed $6.5 million this season after general manager Reggie McKenzie restructured his deal.

(The 2015 conditional pick — also a fifth-rounder — is voided because Flynn won’t be on the 2015 roster.)

Flynn opened training camp as the Raiders’ starting quarterback, but would lose that job to Terrelle Pryor, just as he lost the Seahawks job in camp a year ago to Russell Wilson. There have been whispers that Flynn was moping around in meetings and the locker room and he was demoted to third-string behind undrafted rookie Matt McGloin last week.

“I don’t know exactly what the reason was. Why it didn’t work … it just didn’t work,” Raiders coach Dennis Allen said Monday. “Terrelle came in and took over the job.”

The Raiders are bringing in veteran backups David Carr and Pat White in for workouts in the next couple of days.

Flynn started for an injured Pryor (concussion) in Week 4, completing 21-of-33 pass attempts for 227 yards with one touchdown and an interception in a 24-14 loss to the Redskins. Flynn was also sacked seven times and lost a pair of fumbles.

Cutting Flynn is a $2.6 million hit on the Raiders’ salary cap.

Flynn has banked $14.51 million from the Seahawks and Raiders over the last two years, starting just one game.
